Try and experiment with using a screen. If you are exiting off a friendly controlled map edge, then throw a screen out in front while ordering the bulk of your force to exit. IF you are to exit from an enemy controlled location, then use a screen on your flanks to prevent the enemy from engaging your main body and use an advance guard group to attack through to the exit, then issue an exit order to your main body.
This will work if none of those 3 forces is in combat, otherwise it will bog down on the first contact with the enemy, and unless the scenario is very long or the flankers are very strong, they will never make it to the exit. For example, in one game of "Peiper crosses the Meuse", I managed to exit the first German KG that enters the South of the map by going across the undefended Ardenne Bridge and running off the map, because there were no US units along that road yet. But in another iteration where I had KG Peiper go around the Ardenne bridge to get behind the enemy at the Huy bridges (which had both been blown), I was unable to exit ANY of the KG Peiper units despite the fact that most were between the enemy and the exit point, and the only enemy units in the way were a couple of supply units and an artillery. I gave the exit order over 2 days before the end of the game, but KG Peiper hardly moved at all.(I posted a picture of the situation in the thread on this subject in the war room area).
I suspect that this may be because some of KG Peiper units were in combat and the rest of them would not run away without those units. Maybe detaching the units that are not free would help? Or perhaps the bypass command is not strong enough? As far as I could see, it has no effect at all when enemy units are in the way. It seems to me that a battalion or stronger force should be able to brush right by an enemy supply unit if it wanted to, especially if it has tanks.
In the exit scenarios I have played so far (for example Hell on Wheels and Peiper crosses the Meuse, clearing a road to the exit point as you describe is equivalent to winning a decisive victory.
EDIT: The withdraw command works. Check out the thread on this subject in the War Room section for details.
